Variable air volume terminals, single duct, parallel and series fan terminals provide zone comfort, part load humidity control and low operating costs. Combination dual duct boxes with both preconditioned outside air and return air VAV valves assure proper outside air distribution at all load conditions. Dual duct fan terminals with preconditioned outside air and return valve serve perimeter spaces. Sensible only cooling coils in fan powered VAV terminals, along with DOAS equipment, reduce fan operating power as well as air duct sizes and costs.
